Joerger Enterprises VTR10014 Analog Digitizer with Oscilloscope Characteristic

The Joerger Enterprises VTR10014 is a 6U VME analog digitizer module delivering real-time signal acquisition with oscilloscope-grade input characteristics. Available in 1, 2, 4, or 8 channel configurations, each channel digitizes at 100 MHz with 14-bit resolution and 512K words of dedicated SRAM. Signal averaging from 2 to 128 samples improves SNR for precision measurement. The module accepts single-ended or differential inputs at 10 MΩ impedance with adjustable full-scale offset control and multiple trigger modes - post-trigger, multiple post-trigger, pre/post-trigger, and multiple pre/post-trigger - sourced from front panel input, VME command, or selected channels. Trigger events capture both address and real-time arrival data with programmable active-mode delay and selectable event register thresholds.
